A budget cap with a following
Kiierr built its following on lower-priced laser caps with high laser counts, and it's popular on Reddit and YouTube. The Kiierr 272 uses about 272 lasers at roughly 650 nm, with sessions around 30 minutes every other day. It is FDA-cleared for androgenetic alopecia.
What you give up
It is a lasers-only cap, so there are no LEDs. As a smaller brand, it has a shorter track record and less published clinical data of its own than HairMax or iRestore. VERIFY
Who it's for
Budget shoppers who want a cap they can wear under a hat and don't mind a 30-minute session. See how it compares in iRestore vs Kiierr and our best budget device ranking.
Verdict
A solid budget cap. If you can stretch your budget slightly, iRestore adds LEDs, full-scalp coverage and a more established brand.
